If you are familiar with game boy, the gaming company by Nintendo, then i have a question for you. This also applies to any eletronic device with a circuit board. It might not actually be a circuit board -- I don't know what it is called. But it is green and has alot of connections on it. How do they work? How do you get the programming code (instructions) on these? How does the eletricity flow through them? I don't understand circuit boards, and would like some help on this area. Thank you.
